Month: April 2025

In the 3-2-1 format of the newsletter, I’m posting a few essential articles to revisit, updates to know about, and one question to ponder:

Three short articles to revisit:

• Whether you use RxJs Subjects or Angular Signals for reactivity, using the right visibility modifier in TypeScript can help you expose your application state in a safe, read-only manner. These articles highlight the “why” and the “how” of visibility modifiers. They also cover different interesting syntax options.

Two Angular updates worth knowing about:

• Angular is evolving rapidly, and new APIs are introduced with both minor and major versions. Some are experimental, some are in developer preview, some are stable, while others get deprecated over time. With Angular Can I Use, you can know the status of any feature in just seconds:

• The recording of Geekle’s Angular Global Summit is now available for free on YouTube. With talks from Manfred Steye, Stephen Flui, yours truly, and many others, I’m sure you’ll find interesting talks in that video!

One question to ponder

• Did you know that with the new @for block, you don’t need to declare local variables? You can use $even, $index, and other contextual variables directly:
  
  Instead of this:
  @for (item of items; track item.id; let idx = $index) {
{{idx}} - {{item.name}}
}
  
  You can do just the following:
  @for (item of items; track item.id) {
{{$index}} - {{item.name}}
}
